The prototype of this JSM Special Edition helmet was designed using 3D technology and intended to show the inside of this well-known helmet for diorama and model scenes (rather than being placed on a figure head).

Here I have gone to the limits in creation and casting and this item is quite thin in places. Care should be taken when handling / painting, as the helmet thickness is very thin. The gaps underneath the helmet liner are filled out and the casting is in the normal light grey resin.
